Genus and species: Dianthus caryophyllus L.

Variety denomination: ‘KLEDG20339’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dianthus,botanically known as Dianthus caryophyllus L., and hereinafter referredto by the variety name ‘KLEDG20339’. ‘KLEDG20339’ originated from acontrolled cross in May 2015 in Stuttgart, Germany between theproprietary female Dianthus parent ‘DSS-2014-1001’ (unpatented) and theproprietary male Dianthus parent ‘DSS-2014-1007’ (unpatented).‘KLEDG20339’ was selected in July 2016 from a population of plants grownresulting from the initial cross.

In August 2016, ‘KLEDG20339’ was first vegetatively propagated byvegetative stem cuttings in Stuttgart, Germany and Latina, Italy.‘KLEDG20339’ was found to reproduce true to type in successivegenerations of asexual propagation in Latina, Italy and Stuttgart,Germany via vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of ‘KLEDG20339’ when grown under normal horticulturalpractices in Stuttgart, Germany.

-   -   1. Light pink with dark pink macules, double flowers; and    -   2. An upright habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Dianthus plant is illustrated by the accompanying photograph ofan 11-week-old plant taken in April 2018 and grown in a greenhouse inStuttgart, Germany. The colors shown are as true as can be reasonablyobtained by conventional photographic procedures.

The photograph is a whole plant photo of ‘KLEDG20339’ and shows thefoliage, buds, and flowers.

DESCRIPTION

The following detailed descriptions set forth the distinctivecharacteristics of ‘KLEDG20339’. The data which define thesecharacteristics were collected from asexual reproductions carried out inStuttgart, Germany. Data was collected in March 2022 from plants thatwere 6-months-old and grown in a plastic greenhouse. Color referencesare to The R.H.S. Colour Chart of The Royal Horticultural Society ofLondon (R.H.S.), 5^(th) edition (2007).
